OPA830IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA830IDR is a single-channel high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.8 V to 11 V, with a maximum rating of 11 V. Key electrical parameters include a gain-bandwidth product of 110 MHz and a slew rate of 550 V/µs. The device delivers an output current of 85 mA per channel while maintaining a low quiescent current of 3.9 mA. Input specifications feature a voltage noise density of 9.2 nV/√Hz, an input bias current of 13 µA, and an input offset voltage of 1.5 mV. It offers rail-to-rail input and output capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'IDR' corresponds to the SOIC-8 surface-mount package and tape-and-reel shipping format. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure thermal management aligns with the specified operating temperature range of -40°C to +85°C for reliable long-term performance in the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between high bandwidth (110 MHz) and low power consumption is required. It is suitable for designs needing rail-to-rail I/O without dual supplies. Compare against the OPA810 if higher output current or lower noise is needed, or against the OPA2836 if lower power at similar speeds is prioritized. Validate that the 1.5 mV offset voltage meets system accuracy constraints.
